Exact Answer

==================================================
Problem: What is 2/14 plus 7/39?
Formula / Expression: 2/14 + 7/39
Final Answer: 88/273
==================================================

Step-by-Step Solution:

Step 1: Find the Least Common Denominator (LCD)
The denominators 14 and 39 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 14 × 39 = 546.
Working: LCD(14, 39) = 546

Step 2: Convert to Equivalent Fractions with Common Denominator 546
Multiply the numerator and denominator of 2/14 by 39, and multiply the numerator and denominator of 7/39 by 14 so both fractions share the common base 546.
Working: 2 × 39/14 × 39 = 78/546 and 7 × 14/39 × 14 = 98/546

Step 3: Add the Numerators
Now add the numerators (78 + 98 = 176) and keep the common denominator 546 unchanged.
Working: 78 + 98/546 = 176/546

Step 4: Simplify the Fraction to Lowest Terms
Find the Greatest Common Divisor (GCD) of 176 and 546, which is 2. Divide both the numerator and denominator by 2.
Working: 176 ÷ 2/546 ÷ 2 = 88/273

Step 5: Decimal & Percentage Representation
Dividing the numerator 88 by denominator 273 produces a repeating decimal (approximately 0.322344, or 32.2344%).
Working: 88 ÷ 273 = 0.322344 (32.2344%)

Key Values:
- Simplified Fraction: 88/273
- Mixed Number Form: 88/273
- Decimal Value: 0.322344
- Percentage: 32.2344%

Step-by-Step Solution: 2/14 + 7/39

Step 1

Find the Least Common Denominator (LCD)

The denominators 14 and 39 are coprime (they share no common factors other than 1). Therefore, their Least Common Denominator (LCD) is simply their direct product: 14 × 39 = 546.

LCD(14, 39) = 546

Step 2

Convert to Equivalent Fractions with Common Denominator 546

Multiply the numerator and denominator of 2/14 by 39, and multiply the numerator and denominator of 7/39 by 14 so both fractions share the common base 546.

2 × 39/14 × 39 = 78/546 and 7 × 14/39 × 14 = 98/546

Step 3

Add the Numerators

Now add the numerators (78 + 98 = 176) and keep the common denominator 546 unchanged.

78 + 98/546 = 176/546

Step 4

Simplify the Fraction to Lowest Terms

Find the Greatest Common Divisor (GCD) of 176 and 546, which is 2. Divide both the numerator and denominator by 2.

176 ÷ 2/546 ÷ 2 = 88/273

Step 5

Decimal & Percentage Representation

Dividing the numerator 88 by denominator 273 produces a repeating decimal (approximately 0.322344, or 32.2344%).

88 ÷ 273 = 0.322344 (32.2344%)
